Photograph of a newspaper advertisement for the California Fruit Growers Exchange, ca.1920. The advertisement consists of a paragraph of information at center surrounded by the outline of an orange. In the lower right corner is a drawing of the distinctive wooden crates used by the California Fruit Growers Exchange. The text of the ad reads as follows: "Ask for California Oranges in this style box. Then because oranges vary -- demand the best to be had -- packed by California Fruit Growers Exchange -- a co-operative organization which includes 4,000 owners of the most highly cultivated California orange groves. The Exchange markets only the pick of the crop -- selected, hand-picked, tree-ripened, full-flavored, cleaned and sorted oranges. This box is your protection. Oranges are prescribed by physicians for their tonic value -- as an aid to digestion, and because of their laxative action, they give balance to any meal. California Navel Oranges are Seedless".
